The IPAQ instruments have acceptable measurement properties, at least as good as other established self-reports. Considering the diverse samples in this study, IPAQ has reasonable measurement properties for monitoring population levels of physical activity among 18- to 65-yr-old adults in diverse settings. The short IPAQ form "last 7 d recall" is recommended for national monitoring and the long form for research requiring more detailed assessment.

Sedentary behavior should be explicitly measured in population surveillance and research instead of being defined by lack of physical activity.

Intervention exposure resulted in increased frequency of PA and walking for exercise in postnatal women.

Objective: To assess the test-retest reliability and validity of a modified selfadministered version of the Active Australia physical activity survey.
